This modular mini planter system allows for the creation of a wide range of unique configurations. Water is shared through the system, flowing from the top planters into the bottom, saturating the soil of each plant along the way. These planters are perfect for air plants, succulents, or any small plant that requires little soil. Includes 10 planters, 3 double channel planters and 7 single channel planters. Individual planters are also available.
